These very handsome renderings come from NCRS reader Obiboi's (oberam bezzi design) great blog Motosketches. Full of incredible concept designs, his work is clean, well though out and very well grounded. Our personal favorite is the Great Chaparral racer-based work. (above)
The world weeps that Audi has never considered building a bike, and that Obiboi has not been asked to design them-yet.
